October 11, 2006 An upgraded version of the iconic Vertical Take-Off and Landing (VTOL) Harrier GR9 aircraft has entered service with the United Kingdom’s Royal Navy and Royal Air Force after a GBP500 million improvement package. The GR9 programme provides updated digital systems and enhanced operational capability that will allow the RAF to hit a wider range of targets harder, at longer range, with greater precision and with less risk to aircrew. A number of new systems have been or will be integrated onto the GR9, linked by a new on-board computer. These include the Precision Guided Bomb and infra red & television variants of the Maverick missile. Also included is the Successor Identification Friend or Foe (SIFF) system, which will make the aircraft less vulnerable in an operational environment. The GR9 will also carry the Brimstone missile which will enable it to attack up to 12 ground targets simultaneously compared with just two with the GR7.
